In Indian state governments moves to gnu Linux as windows xp expired. Indian state tamilnadu has already post circular to offices to move on gnu linux.
The Indian newspaper The Hindu reported last month that
the Information Technology department had issued an order
which said, in part: "Consider installing BOSS [Bharat
Operating System Solutions] Linux as one of the mandatory
operating system."
India decided three years ago to launch a new ICT policy
based on the mandatory use of open source operating
systems. In November 2011, Tamil Nadu introduced BOSS
GNU/Linux, a derivative of Debian GNU/Linux, to be installed
and used on government computer systems.
BOSS GNU/Linux has support for all major Indian languages,
bio-sensing devices and digital signatures.
As The Hindu pointed out, apart from the cost savings, it was
the reduced risk of being infected by viruses or affected by
hacking or phishing attacks that led India to introduce the
new operating system.
